With thermostat control adjustable venting, anti-odor padding, and a customizable fit at the turn of a dial, the all-new Union MIPS Helmet comes fully loaded for your all-mountain freeriding.

In-mold construction and adjustable venting create a lighter, cooler helmet making Union MIPS ideal for both ascending and descending the slopes.

When things start to heat up, you can go the distance in comfort, as the XT2 anti-odor protection will prevent your helmet from getting stale, and the adjustable In Form Fit System will let you customize your fit at the turn of a dial. Rest easy knowing that the Multi-directional Impact Protection System (MIPS) can provide more protection in certain impacts.

- Thermostat control adjustable venting allows you to custom tune airflow instantly with a simple, low-profile control button on the outside of the helmet Stack Vent™ Technology

Fit System:
- The In Form™ Fit System makes it easy to dial in a custom fit in seconds - even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability.

- 465g (size medium)

- CE EN1077

Size Guide


Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.

Small 52 - 55.5 cm
Medium 55.5 - 59 cm
Large 59 - 62.5 cm
X-Large 62.5 - 65 cm

Note: We recommend you try helmets on before buying. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering vision. Once you’ve got the right size, you can adjust the fit.


Step 1: Adjust the fit system at the rear of the helmet for a snug, secure fit. Some helmets also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.

Step 2: Adjust the straps so that they sit just below the earlobes.

Step 3: Adjust the buckle so that it rests against the back of the jaw/throat.

Step 4: Adjust the interior pads if needed.

Step 5: Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.
